Re: What is this thing below the tiller?
Given the geometry of the shaft, that appears to be a way to turn the trim tab with the shaft passing diagonally through the rudder itself. I have seen that type of thing before but usually the tiller for the trim tab is much shorter and set up so it could be tied into a windvane. You would normally expect to see small turning blocks on either side of the trim tab tiller that would have been led to the vane, but there is no sign of that hardware.
I have also seen trim tabs set up so that they balance weather helm, but those usually have a small quadrant mounted below the tiller that allows a fixed setting.
In any event, that boat needs a new tiller badly.
